UNITED STATES THOMAS HARTLEY, OF BRIDGEPORT, OHIO.

IMPROVEMENT IN STOVE-PIPE ELBOWS.

Specification forming part of Letters Patent No. 123,992, dated February27, 1872.

To all whom it may concern:

Be it known that I, THOMAS HARTLEY, of Bridgeport, in the county ofBelmont and State of Ohio, have invented a certain new and usefulImprovement in Stove-Pipe Elbows and I do hereby declare the followingto be a full, clear, and exact description thereof, reference being hadto the accompanying drawing forming a part of the same, and in whichFigure 1 represents a perspective view of the lower section of my elbow;and Fig. 2, a similar view of the upper section thereof. Fig. 3 is aview of the same, partly in section and partly in side view; and Fig. 4,avertical central section thereof, illustrating it as applicable to anupright pipe, the figure mentioned next before this showing it asapplicable to a horizontal pipe.

Similar letters of reference in the several figures are used todesignate corresponding parts.

This invention has reference to an improved stove-pipe elbow; and itconsists of the parts of which itis constituted, when so constructed asthat they shall form an elbow which shall be applicable to a horizontalpipe, and permit of being reversed, by which an elbow applicable to anupright pipe is formed, substantially as hereinafter more fully setforth and claimed.

To enable others to make and use my invention, I will proceed todescribe it.

In the annexed drawing, A refers to the lower section of my elbow, whichis constructed with flanges a a, through which screw-bolts with nuts aredesigned to pass for fastening said section upon the stove. The upperend or extremity of this section is made into an inclined plane, andupon the ends of the same are formed flanges a a, having apertures. Brefers to the upper section or half of the elbow, the lower end orextremity of which is an inclined plane, and hasflanges I) I), throughwhich scrcws pass, entering the flanges a a upon the section A, andsecuring it thereupon.

The curvature and inclined planes given these parts or sections are suchas that when they are brought together, as shown in Fig. 3, an elbowwill be formed such as is applicable to a horizontal stove-pipe, while,at the same time, they can be reversed, and an elbow formed suitable foran upright pipe, as shown in Fig. 4.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is

The section A, with flanges a, in combination with the section 13,having flanges b b, all constructed and arranged, to form a curvedreversible stove-pipe elbow, substantially as described and shown.

In testimony whereofI have hereunto signed my name this 4th day ofAugust, A D. 1871, in presence of two subscribing witnesses.

THOMAS HARTLEY.
